Although I am a convinced atheist, I don't want to get into a big argument because it usually get me mad and makes me say bad stuff. I just want to point out, regarding the begining of the universe, that it is possible for something to pop out of nothing; as long as an exact opposite is created. Kinda like how 1 and -1 together makes 0. Last time I checked I think thats how science explains the begining of the universe. I think I've also read that some matter and corresponding anti-matter gets created out of nothing near blackholes sometimes.
I just thought that it would be helpful to point out the fact that something coming from nothing has never been observed. It also seems that if the univserse has an opposite, then it has created the illusion of consciousness. An illusion is something. Also, it might be observed that there are different kinds of opposites. Some opposites cannot exist without the other, while some can. For example, tall cannot exist without short, because these are what I usually call "opposites of relation". Tall and short are two sides of one thing (i.e. height). Tall and short cannot exist on their own; however, this does not mean that height does not exist.
[EDIT] I'll use logic to prove that god doesn't exist. If god is god, then he can do anything. If he can do anything, then he can build a room he cannot get out of. If he can create such a room, then he can't do anything. Therefore god does not exist.
I want everyone to know that I mean no offense, but this is not logical at all. Let us observe what we are doing here. We are assuming that God is only God if he is omnipotent. A divine being may not need to be omnipotent to exist. But let us take a look at this divine omnipotence. The word, omnipontence, is usually used to mean "the ability to do all or everything". Now, when we use the word "imopossible", we usually imply a supressed clause beginning with the word "unless". (e.g. it is impossible for me to get up my stairs with a broken leg, unless I have some help from my friends). Some statements, however, carry their impossiblities within themselves. These intrinsically impossible events are even impossible for omnipotence. (e.g. We cannot say that God both exists and does not exist). To say that God can give a creature free will and at the same time withhold free will from that creature, you have said nothing about God. "Meaningless combinations of words do not suddenly acquire meaning simply because we prefix to them the two other words 'God can'." This is no limit to His power. Omnipotence is the power to do all things, but intrinsically impossible events are not things but non-entities. In the words of C.S. Lewis, "...nonsense remains nonsense even when we talk it about God."
The Problem of Pain, p. 18.
Well, it is possible for stuff to pop out of nothing in very rare cases, anomalies.
I do not see the logic in thinking that something can come from nothing. I have never heard of such a thing ever being observed. It seems that the fundamental difference between theists and atheists is that theists believe that a being created, but atheists believe that matter created. Both accept that something always was. I would assume that a theory about something coming from nothing could be created and accepted only by someone who refuses to believe in a divine being and was looking for a different explanation than matter always existing. Perhaps they see the discoveries that science has produced and have concluded that there was a time when matter did not exist, yet did not want to believe in a divine being that they could not observe physically, either. I am sure that there are many other kinds of people who believe such things and for many different reasons. I am only speculating. I do think, however, that to say that something can come from nothing is neither logical nor scientific.
